Title: Recorded medium reproducing apparatus
Inventor: NONAKA YOSHIYA
IPC: G11B20/10
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a wait time after a reproduction start is instructed before sound is output and obtain a recorded medium reproducing apparatus with superior vibration resistance, by controlling the remaining amount of a memory by means of a microcomputer. SOLUTION: Since the amount of data stored in a memory 7 and the threshold are both 0, the apparatus reads data at the double speed of a normal reproduction speed and a microcomputer 8 resets the threshold from 0 to a predetermined initial value when the reproducing apparatus receives a reproduction instruction. Read RF signals are supplied to a vibration-resistant memory controller(TMC) 6 via a control circuit 5. The TMC 6 supplies the data to the memory 7, and simultaneously with this, reads out data at the normal reproduction speed and feeds to a D/A converter 9. When the remaining capacity of the memory 7 is saturated, the microcomputer 8 stores an address of the data when the memory 7 is saturated and stops the reading. When the remaining capacity of the memory 7 reaches the threshold value, the reading is resumed.  The threshold value can be varied by the microcomputer 8 is accordance with a missing time or missing frequency of output data.

Title: Preservation bag for cereals
Inventor: CHIKAMORI YOSHIHIRO
IPC: B65D81/26
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To enable the humidity control effect in a storage house to be brought also into the preservation bag for cereals through a sheet material, by using the sheet which has a moisture permeability but has not an air permeability for a part or the whole of the material constituting the bag, which is filled with cereals and kept in a storage house for preservation. SOLUTION: This preservation bag is formed of a sheet which has a moisture permeability but has not an air permeability as a whole. This sheet prevents air (oxygen) from penetrating the preservation bag. When the vapor pressure in the preservation bag is higher than that of the surroundings of the storage house, the vapor is diffused to the outside of the bag and to the contrary, when the vapor pressure in the bag is lower than that of the surroundings, the vapor is taken in from the outside of the bag. In this way, the humidity in the preservation bag is kept nearly equivalent to the humidity in the storage house with an adjusted humidity. And hence, dew drops in the bag inside generated owing to the change of humidity is prevented.

Title: Measurement of modified hemoglobin
Inventor: MIURA KEISUKE
IPC: G01N33/531
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To measure modified hemoglobin even in low concn. with high sensitivity by allowing a water-soluble compd. among polyethylene glycol, polyvinyl pyrrolidone, pullulan and dextrane to be present in a hemolytic sample. SOLUTION: When modified hemoglobin is measured by immunoagglutination reaction, at least one water-soluble compd. selected from the group consisting of polyethylene glycol, polyvinyl pyrrolidone (weight mean mol.wt.; about 3,000-1,000,000), pullulan and dextrane (weight mean mol.wt.; 1,000-1,000,000) is allowed to be present in a hemolytic sample to be used. If a mol.wt. is too small, the enhancement of sensitivity is insufficient and, if too large, solubility becomes bad. The concn. of the water-soluble compd. is set to about 0.01-10% (w/v) of a reaction system. If the concn. of the water-soluble compd. is too low, sensitivity is lowered and, if too high, non-specific reaction is generated and accurate measurement becomes difficult. By this method, the sensitivity of immunoagglutination reaction can be enhanced drastically.
